The main reasons for grinding flanges and pipe ends during the installation of wear-resistant ceramic pipes are as follows: 1. Ensure sealing Flange grinding: Flanges are key components that connect pipes, equipment, valves and other components in the pipeline system, and their sealing performance is crucial. Grinding the flange surface can remove burrs, dirt and oxide layers on its surface, thereby ensuring that the flange surface and gasket can fit tightly to form an effective seal. This helps prevent medium leakage and ensures the safe and stable operation of the pipeline system.   Pipe end grinding: Similarly, grinding the pipe end can remove unevenness and impurities on its end face, ensuring a tight fit between the pipe end and the flange or other pipe connectors. This helps reduce the risk of leakage and improve the overall sealing performance of the pipeline system.   2. Improve connection strength Flange connection strength: By grinding the flange surface, the contac...

1. The fixing method of bolt column type chemshun  wear-resistant ceramic lining is to connect with the bolt column. The height of the countersunk hole at the head of the bolt column is generally half of the thickness of the ceramic lining. Therefore, when the wear-resistant ceramic lining is worn to half, the bolt can no longer play a downward fixing role, and only the adhesive force of the glue is working. 2. The fixing method of welded wear-resistant ceramic plate is to fix it by gluing and iron bowl welding. As long as the iron bowl is not worn off, the welded wear-resistant ceramic plate still plays a downward fixing role. There is still a dual fixing effect of iron bowl and gluing. Construction method comparison:   1. The fixing method of bolt column type wear-resistant ceramic plate is to connect with gluing and bolt column. Construction process: drilling steel plate, applying glue, and fixing bolts. The disadvantage is that the steel plate needs to be drilled manually...

There are differences in performance between chemshun wear resistant ceramic liner tile  with 92% aluminum content and 95% aluminum content, as follows: * Hardness. Wear-resistant ceramic sheets with 95% aluminum content have higher hardness than 92%, which improves their wear resistance to a certain extent. Therefore, the degree of hardness may affect the durability of wear-resistant ceramic sheets. , * Brittleness and degree of dome. In addition, wear-resistant ceramic sheets with 92% aluminum content are relatively tough, while wear-resistant ceramic sheets with 95% aluminum content may be more brittle and may crack during bending or use. This may affect its performance in practical applications. * Price. Wear-resistant ceramic sheets with 95% aluminum content usually have higher production costs due to their higher aluminum content and hardness, which affects their market prices. In general, these two types of chemshun wear-resistant ceramic plate have their own unique charact...

Toughened oxide wear - resistant ceramics are a new type of toughened oxide wear-resistant ceramics. Compared with ordinary alumina wear-resistant ceramics, toughened oxide wear-resistant ceramics have achieved a major breakthrough in performance.   Ordinary alumina wear-resistant ceramics are sintered from high-purity alumina powder and have good hardness and wear resistance, but their toughness is poor and they are prone to breakage when impacted, which limits their application in some fields that require high material toughness. Toughened oxide wear-resistant ceramics add zirconium oxide and other substances to alumina. In this way, the toughness of the material is significantly improved, and it also has good thermal shock resistance. In practical applications, toughened oxide wear-resistant ceramics can withstand greater external force impact without breaking, and their service life is greatly extended. The emergence of toughened oxide wear-resistant ceramics is expected to pro...

  The packing is divided into random   tower  packing and structured packing. What should be paid attention to when installing random packing? It is estimated that many people are not very clear.   The stacking of bulk packing is generally not affected by the ellipticity of the tower. In order to facilitate the stacking of random packing into the tower, it is generally placed in a random pile. The recommended error of the conventional random packing tower can be found in the corresponding standard. Generally, after the design is completed according to the standard, the manufacturing and parameters of the packing are also provided by the manufacturer. Sometimes the purchased random packing needs to be processed before use.    There are two methods for loading random packing in the tower: wet loading and dry loading. The so-called wet loading is to fill the tower with water (or process liquid) first, and then load the packing tower packing. This method has a...
